GATE.

Application filed. September 27, 1922.

To all whom 2'25 may concern.

Be it known that 1, JOHN B. ADAMS, a citizen of the United States, residing at Loxley, in the county of Baldwin and State of Alabama, have invented certain new and useful Improvements in Gates, of which the following is a specification.

This invention relates to new and useful improvements in gates and more particularly to the opening and closing mechanism therefor, the primary object of the invention being to provide a vertically swinging gate having means associated therewith which will automatically shift to position on opposite sides of the gate pivot, so that proper force can be applied to the gate for opening or closing the same and also serve as a means for cushioning the downward movement of the gate to obviate jolts and jars thereto.

Another object of the invention resides in the provision of a gate of the above mentioned character embodying a construction for operating the same which is compact, simple in construction and one which is durable and efficient in practice.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the several views,

Figure 1 is a front plan of the gate showing the same in a closed position in full lines, and an open position in dotted lines,

Figure 2 is a end elevation of the gate in closed position, and

Figure 3 is a transverse section through the carriage. ,7

Referring now to the drawings, wherein for the purpose of ill st ation is shown the embodiment of the invention which is at present preferred, the numeral 4 designates a gate hinge post, which in the present instance consists of a pair of spaced posts between which the gate 6 is pivoted and adapted to swing. The lower corner of the gate adjacent the posts 5 is provided with a coupling 7 having an apertuled ear extended therefrom to be arranged between the lower ends of the posts 5 so as to be pivoted therebetween by a bolt or rod 8 extended through both posts. The gate opens by swinging vertically between the two posts 5, and the Serial No. 5905910.

means for moving the gate to an open or closed position from either side thereof consists of a cable or flexible element 9 for each side of the gate having its lower end associated with the gate and its upper end connected to the inner end of a lever 10 fulcrumed as at 11 on a support 12 so that the outer end 13 of each lever will be spaced from the gate post, and may if desired be provided with a depending cable 1 1 arranged within reach so that the lever can be manually operated.

The support 12 for each lever in the present instance consists of an inverted V-shaped standard, one arm of which is fastened to the top of its respective post 5, while the other arm of the \l-shaped standard is secured to the side of its post adjacent its lower end, the latter arm forming a substantial brace for fulcruming its respective lever a distance from the gate proper. As is obvious, the levers 10 are arranged to extend alongside and parallel to the side of the road leading to the gate so as to be accessible to the driver of a vehicle passing through the gate.

As shown to advantage in Fig. 1 it will be seen that the gate when in an open position is arranged with its longitudinal dimension upright, and with one edge disposed in close proximity to the ground. In order that the cables 9 can exert a proper force on the open gate to swing it to a closed position, each side of the gate adjacent its lower corner which is pivoted to the posts 5 is provided with a pair of diagonal inclined bars 15 arranged in vertical spaced relation as shown. One end of each bar is attached to the inner end of the gate, while the other end thereof is fastened to the lower bar of the gate, so that the four diagonal bars provide the gate 'ith an inclined track. The means provided for shifting the pull of the cable 9 to different parts of the gate consists of a carriage which is designated in its entirety by the numeral 16. This applicator consists of a pair of triangular shaped plates 17 one arranged on each side of the gate and on the outside of the diagonal bars 15, and these two plates are connected by a pair of bolts 18 which extend through a pair of rollers 19 clearly shown in Fig. 3, which extend through the pairs of diagonal bars 1:) and are guided in their movement thereby. The relative upper end of each plate 17 is provided with an eyelet 20 to which the lower end of its respective cable 9 is attached.

When the gate 6 is in a closed position it will be seen that the track 15 inclines downwardly and outwardly of the gate posts 5, so that the carriage 16 is caused to roll by gravity down the inclined track to be disposed far enough from the gate pivot 8 so that an upward pull on either cable 9 will swing the gate 6 in an arc of a circle between the two posts 5, to an open position. lVhen the gate has been swung to an open position so as to be stood on its inner end, what was the bottom of the track, now becomes the top so that the carriage 16 rolls down the inclined track to be disposed far enough from the gate post and the pivot 8 sothat an upward pull on either cable 9 will swing the gate to a closed position. It will therefore be obvious that a downward pull on the outer end of either lever 10 will cause the gate toeither open or close depending upon the position of the gate at the time the lever is swung. Therefore when a vehicle approaches the gate and the gate is closed, the flexible element It by the lever adjacent the vehicle is pulled so that the flexible element 9 exerts an upward pull on the gate to swing the same to an open position. After the vehicle has passed on and it is desired to close the gate after the vehicle, the lever 10 adjacent the vehicle is operated to cause the cable 9 to pull upwardly on the gate thereby causing the same to swing to a closed position, and as the gate is moving toward this position the carriage is rolling down the inclined track sothat the downward swinging movement of the gate can be retarded by holding on to the flexible element 1 1 after the center of gravity of the gate has passed the perpendicular. Consequently in either opening or closing the gate its moving can be retarded after it passes the perpendicular so that the gate will not jar or jolt. The applicator 17 is heavy enough to overcome the weight of the long ends of the pull levers.

Having thus fully described my invention, what I claim is 1. A vertically swinging gate, a pair of vertically spaced bars rigidly attached to and extending diagonally across the lower corner of the gate to provide a track, a carriage including a roller mounted between said bars, and a cable connected to said carriage for opening or closing the gate.

2. A vertically swinging gate pivoted at its lower inner corner, a pair of vertically spaced bars rigidly attached to the gate and extending diagonally across said lower corner of the gate, a carriage including a pair of spaced rollers mounted between said bars, and a cable connected to said carriage for opening or closing the gate.

3. A vertically swinging gate, a pair of vertically spaced bars rigidly attached to said gate and extending diagonally across the same to provide a track, a carriage including a pair of triangular plates arranged upon opposite sides of said track, a pair of rollers journaled in a pair of the corners of said plates and extending between said bars forming the track, and a cable connected to the apex of each triangular plate above the track for opening or closing the gate.

In testimony whereof I affix my signature in presence of two witnesses. 7
